Genome of eukaryotic cells contains up to 69% of the transposable elements and repetitive sequences. To a large extent it is a result of billions of years of evolution through which eukaryotes were encountering gazillions of viruses and storing the footprints of those encounters in its genome. This time Mankind deals with a novel virus belonging to the coronavirus family, which albeit being widely spread in the wildlife is new to humans. Once infected, 80% of humans experience a flu-like symptoms and eventually recover. However, the real menace is posed to those whose vulnerability is determined by old age and underlying medical conditions.
